DRINK-DISPENSING AriumATUs.

Application filed .Tune 28,

To all whom it may concern:

Be it known that 1, CHARLES C. GATES, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Drink-Dispensing Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use'the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in drink-dispensing apparatus and, to be more specific, comprises .a rotary head operated by an electric motor, the construction being mounted in a' casing, and open at the end adjacent the head to permit the introduction of the hand of the operator in order to place the fruit, as half an orange, into contact with the rotary head,which is also longitudinally slidable on its shaft, whereby a valve is operated to allow'liquid to be brought into contact with the head, and the fruit, all of which passes through an outlet into a glass or other receptacle. Furthermore, the valve operated by the head as. aforesaid, is located in a casing which communicates with a number of pipes, each of which is in communication with a source of liquid under pressure, whereby the liquid which is dispensed at each operation of the head may be taken from any one of the pines, as desired, by simply pressing a but ton which controls the passage of liquid through each pipe, the construction being such that the movement of the push button in the first instance closes the motor circuit, bu by further pressure the valve controlling the passage of liquid through the desired tube is opened.

Having briefly outlined my improvement, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof. In this drawing:

Figure 1 is a vertical section taken through my improved drink-dispensing apparatus.

Fig. 2 is a detail viewof the mechanism for closing the electrical circuit and opening the valve of any one of a plurality of pipes.

Fig. 3 is a top plan view of the apparatus with the upper half of the casing or housing removed.

Specification of Letters Patent. Patented Nov, 16, 1920.

1919. Serial No. 307,419.

Let the numeral 5 designate a housing which, as shown in the drawing, iscomposed of a lower member 6, and an upper member 7. The lower member has a horizontal partition 8, upon which rests an electric motor 9, whose shaft 10 is provided with a sleeve 12 at its outer extremity, this sleeve being fast on the shaft. Splined upon the sleeve between its inner end and a forward shoulder 13, and'slidable on the sleeve is an oval head 14 which is provided with openings of any desired shape. As shown in the drawiiig there are elongated openings 15 located in the rear of the small end of the head, the latter being perforated as shown at 16. These openings allow the pulp and juices of the fruit to pass into and out of the head. Connected with a hub 17, with which the head is provided, is an arm 18, which engages a circumferential groove formed in the hub, thus permitting the head to rotate as pressure is applied to the head, as the fruit is held in contact therewith, the head 14 and arm 18 are moved rearwardly, or toward the left, referring to Figs. 1 and 3, whereby a longitudinally movablestem 19 controlled by a spring 119 is actuated to open a valve 120, the latter being located in a casing 21, which is in communication with a number of pipes 22, 23 and 24, each of which is in communication with a valve casing 123, normally closed by a valve 120, which cuts off the chamber of the casing 123 from a chamber 25, which is in communication with a pipe 26, which leads to a source of liquid under pressure (not shown). The valve 120 is provided with a stem 27, composed of two parts, 28 and 29, the part 28 being secured to a sleeve 30 and the part 29 to a sleeve 31, the two sleeves being held in the expanded relation by a spring 32. A

push button 33, movable in the lower part 34 of the housing, is connected with each .valve stem part 29, and carries a projection 35 in whose path is a switch 36, for

' closing the circuit through the motor 9 by 33 is moved inwardly and its initial movement closes the switch 36 and starts the motor. At the same time the fruit will be applied to the head 14 and the operation of removing the pulp and-juices from the fruit will be quickly accomplished and after or during this operation the valve stem 27 will be further actuated by the push button and sufliciently to unseat the valve 120, whereby the liquid is allowed to enter the chamber 21, the valve 120 being unseated by rearward pressure on the head 14 to allow the liquid to pass through a small spout 39, whereby it is brought into contact with the head and the fruit, the pulp and juices being removed from the head and carried downwardly through an opening 46 into a glass 41, or other suitable receptacle.

During the initial pressure of the push button 33, the part 28 of the stem will be held against movement by the pressure of the liquid on the valve 120 through the pipe 26, which it is assumed, as heretofore stated, is in communication with a source of liquid under suitable pressure for the purpose. However, after the initial movement of the push button which has closed the electrical circuit and put the motor in operation, the further movement of the button will bring the inner extremity of the sleeve 31 into contact with the rear extremity of the sleeve 30, whereby the latter will then be actuated to open the valve 120 through the medium of the stem member 28.

From the foregoing description, the use and operation of my improved drink-dispensing apparatus will be readily understood. 1 y

In the first instance the push button 33 will be actuated sufiiciently to close the electrical circuit through the motor, and the fruit will be applied to the head la a sufficient length of time to remove or loosen the pulp and juices, and after or during this operation, the push button willbe further actuated and the liquid from the proper pipe 22, 28 or 24, allowed to enter the chamber 21 and pass thence through the spout 39 into contact with the head, and thence through the opening 46 into the glass. Release of pressure upon button 33 will allow spring 32 to move stem 29 to break the circuit to the motor; and release of pressure on head 14 will allow spring 119 through stem 19 to restore the head to original position and at the same time close valve 120.
